The ichthyofauna of the Lower Cretaceous Quiricó Formation (Sanfranciscana Basin), Minas Gerais, Brazil, comprises so far taxa like Hybodontiformes (Chondrichthyes), Dastilbe, Laeliichthys, Mawsonia, and isolated Amiidae teeth and Semionotiformes scales. Here we report new remains of a dipnoan tooth plate and its associated pterygopalatine and Lepisosteidae material comprising isolated scales, a hyoid arch, and a partially preserved individual including several scales, vertebrae, neural and haemal spines, pterygiophores, and associated anal fin. Although isolated or incomplete, these new fossils, collected from upper sandstone levels of fluvio-lacustrine deposits, increase the diversity of the ichthyofauna of the Quiricó Formation. This discovery adds important information to the understanding of the relationships of Brazilian and African faunas during the initial stages of the opening of the Atlantic Ocean.

巴西米纳斯吉拉斯州下白垩统 Quiricó 组（Sanfranciscana 盆地）的鱼群包括迄今为止的分类群，如 Hybodontiformes (Chondrichthyes)、Dastilbe、Laeliichthys、Mawsonia, 和分离的 Amiidae 牙齿和 Semionotiformes 鳞片。在这里，我们报告了一个恐龙牙板的新遗骸及其相关的翼腭骨和 Lepisosteidae 材料，包括孤立的鳞片、舌骨弓和一个部分保存的个体，包括几个鳞片、椎骨、神经和血液棘、翼突和相关的臀鳍。尽管是孤立的或不完整的，这些新化石是从河湖沉积层的上砂岩层收集的，增加了 Quiricó 地层鱼群的多样性。这一发现为了解大西洋开放初期巴西和非洲动物群的关系提供了重要信息。
